BYD Dolphin, ATTO 3 and SEAL Charger: Which Power Level Should You Choose?
Different BYD models can have different charging specifications, so choosing a charger based only on the car brand is not enough.
If you are looking for a BYD Dolphin EV Charger, ATTO 3 EV charger, or SEAL EV charger, the first specification to check is the vehicle's maximum AC charging power.

BYD Dolphin Charger
The current Thailand specification for the BYD Dolphin lists Type 2 AC charging at up to 7kW for both Standard Range and Extended Range versions.
This means a 7kW AC charger can be a suitable match for home charging when the household electrical system supports it. A 3.5kW portable charger can still be useful if you normally charge overnight or want a more flexible solution.
BYD ATTO 3 Charger
The Thailand-spec ATTO 3 also lists Type 2 AC charging at 7kW and includes a portable Mode 2 charging cable.
For ATTO 3 owners, a 7kW home charger can therefore be a practical option for regular charging. However, if your daily driving distance is low, a 3.5kW portable charger may already provide enough overnight charging.
BYD SEAL Charger
The Thailand-spec BYD SEAL also lists Type 2 AC charging at 7kW, with higher-power DC charging available for faster public charging.
This illustrates an important point:
AC home charging and DC fast charging serve different purposes.
You don't need a high-power DC charger at home simply because your BYD can accept high DC charging power at a public station.
Should You Buy a 22kW Charger?
Not necessarily.
If your BYD accepts up to 7kW AC, installing a 22kW AC charger does not automatically increase the car's charging speed. Your actual AC charging rate is limited by the vehicle's onboard charger.
Therefore, before buying a 7kW, 11 kW, or 22kW BYD charger, check your vehicle specification first.

Final Takeaway
For popular Thailand BYD models such as the Dolphin, ATTO 3, and SEAL, a 7kW Type 2 AC charger is a logical home-charging option based on their current published specifications.
But the best choice still depends on your daily mileage, electrical installation, and need for portability.
